TRAVELING CONTROL DEVICE FOR VEHICLE
To provide a traveling control device for a vehicle capable of suppressing fuel consumption while preventing a driver from feeling a change of a traveling speed when traveling at a relatively low speed in a state where a traveling load is relatively small.SOLUTION: A traveling control device 10 for a vehicle comprises a pressure sensor 24 which detects a pump pressure Pp. In a case where the pump pressure Pp that is detected by the pressure sensor 24 is equal to or higher than a predetermined first threshold during traveling in a state where a high-speed traveling mode is selected by a traveling mode selection switch 21, a controller 27 makes capacitance of hydraulic motors 14L and 14R relatively large. In a case where the pump pressure Pp that is detected by the pressure 24 is equal to or lower than a predetermined second threshold during traveling in a state where a low-speed traveling mode is selected by the traveling mode selection switch 21, the capacitance of the hydraulic motors 14L and 14R is made relatively small and in accordance with increment of a rotation speed with the capacitance reduction of the hydraulic motors 14L and 14R, at least an engine rotation speed is reduced, such that a traveling speed is substantially fixed before and after the capacitance change of the hydraulic motors 14L and 14R.SELECTED DRAWING: Figure 1
【課題】走行負荷が比較的小さい状態で相対的に遅い速度で走行するときに、運転者が走行速度の変化を感じることなく燃費を抑制できる車両の走行制御装置を提供する。【解決手段】車両の走行制御装置10は、ポンプ圧Ｐpを検出する圧力センサ24を備える。コントローラ27は、走行モード選択スイッチ21により高速走行モードが選択された状態での走行中に圧力センサ24により検出するポンプ圧Ｐpが所定の第１閾値以上である場合に油圧モータ14L，14Rの容量を相対的に大容量とする。走行モード選択スイッチ21により低速走行モードが選択された状態での走行中に圧力センサ24により検出するポンプ圧Ｐpが所定の第２閾値以下である場合に油圧モータ14L，14Rの容量を相対的に小容量とするとともに油圧モータ14L，14Rの容量減に伴う回転数の増分に応じて少なくともエンジン回転数を低減することにより油圧モータ14L，14Rの容量変更前後での走行速度を略一定とする。【選択図】図１
